Application filed December 31, 1919.

To all whom it may concern:

Be it known that l, STEPHEN L. Hninniorr, a citizen of the UnitedStates, residing at Brooklyn in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Supports forReinforcing-Bars, of which the following is a specification.

This invention has for its object the economical production of a supportfor the metallic reinforcing bars of concrete structures which, due toits peculiar features of construction, is extremely light in weight andis characterized by its strength and rigidity when utilized for thepurpose specified.

A further object is the provision of a support of this type constructedentirely of metal wire of such size as to lend requisite strength andrigidity and of such shape as to expedite swift andcompact grouping of aplurality of the supports for convenience in transportation.

With these and other objects in view the invention comprises the novelfeatures of construction, combination of elements and arrangement ofparts which will be more fully described in the following specificationand set forth with particularity in the claim appended hereto.

Figure 1 represents a top plan View of the improved support.

Fig. 2 is an end elevation thereof, and

Fig. 3 is a side elevation.

Referring to the drawing in detail the numerals 5 and 6 indicate pairsof diagonally opposed supporting legs which are in downwardly divergingrelation and the two legs 5 and 6 at each end of the support areconnected by the spacing element 7. The upper terminals of the legs areconnected with substantially semi-circular bar seats or supportingmembers 8 and 9 arranged side by side in such manner as to receive,support and tend to prevent lateral displacement of a reinforcing bartherefrom.

As stated, the entire support is constructed of a single piece ofmetallic wire and in Specification of Letters Eatent.

Serial No. 348,571.

the actual production of the support, the medial portion of the sectionof wire is formed into a semi-circle of proper diameter to accommodatethe reinforcing bar in connection with which the support is designed.for use and the adjacent portions of the wire are bent downwardly andoutwardly providing the two opposed supporting legs 5. From theterminals of the legs 5 the wire is bent angularly in oppositedirections to provide the opposed parallel spacing elements 7 and thesubsequent bending operation the terminals of the wire are directedupwardly to define the second pair of legs 6, the extreme terminals ofthe wire being arranged contiguous to and shaped in conformity with theintermediate semi-circular supportlng member 8. l I

From the foregoing it is evident that I have provided an exceptionallysimple and compact support for relnforclng bars in concrete structureswhich, due to the peculiar disposition of the supporting legs thereof,possesses a high degree of strength and rigidity and is capable of swiftapplication to the supporting bars.

The spacing elements 7 are preferably arched or curved upwardly asclearly illustrated in Fig. 2 to provide prominent mold engaging points12 at the terminals thereof which prevent contact of the medial portionof the spacing elements with the wall of the mold and thus permit theplastic material to flow underneath of the spacing elements concealingthe latter from view.

What is claimed is A reinforcing bar support constructed of a singlepiece of wire and consisting of a semi-circular seat, downwardlydiverging supporting legs therefor, and curved spacing elementsconnecting several of the legs,

the terminals of the wire being bent on each side, contiguous with andshaped in conformity with the seat. 0

In testimony whereof, I aflix my slgnature hereto.

STEPHEN L. HEIDRIGH.
